Are larger caliber rifles naturally less accurate?

[QUOTE="BountyHunter, post: 1066463, member: 12"] I will disagree with some of the posters that say larger calibers are just as accurate for several reasons. I believe it is totally unrealistic to think a 338 is going to shoot with a tuned 223 or 6XC. If it was true we would see them at all the matches; but we don't for very good reasons. 1. Much more time and effort has been spent on higher quality match grade bullets for smaller calibers. Not much work has been done in the 338 arena for example until a few years ago. There are still issues with higher quality brass for example in the big case arena and lots are spotty from one to the other. 2. Smaller calibers are inherently easier to shoot accurately from a bench versus larger boomers. Big boomers have big recoil normally and muzzle blast and it will effect most people more than they are willing to admit. Just a simple fact, that no one shoots SR BR with a 338 and very, very few at LR. I only know of one person shooting a 338 successfully in LR and he had a special run of bullets made for him by a big mftr. After that run of bullets was done, so was his run. However, in your case, I would do more reloading work. Try F215 primers, MRP and MRP2 if H1000 is not working. I and many others have had excellent luck with all three of those powders in multiple 338s. Forget max COAL and try a seating depth experiment to find out where the gun likes them. Start at MAX and work back in big jumps to .120 off from MAX. Go to a rest instead of a bipod for load development work. The bipod just adds another degree of variance to the process. Hint Hint, sort the bullets by base to ogive. 388 bullets are noted for wide variances especially SMKs. [/QUOTE]
